Sizing a Steam Boiler | U.S. Boiler Company

Sizing a Steam Boiler. December 5, 2017. By Ron Beck, U.S. Boiler Company. Last month we discussed sizing a hot water boiler with a heat loss calculation. Unlike a hot water boiler, a steam boiler is sized by determining the square foot of radiation connected to the steam system. Once that’s been determined, you can accurately
